Change button to Remove From Cart after max quantity met

Hi. Nice plugin. The default behavior after max quantity is met for a product is that if you click on the Add to Cart button you go to the single product page and get a notification. I would like to change the button instead to “Remove from Cart.” Then when you click on it the item will be removed from your cart (just like clicking on the Remove button on the actual Cart page).

It’s easy enough to change the text on the button. What I need to change is the behavior when clicked.

Thanks!
